Mitochondrial matrix protein LETMD1 maintains thermogenic capacity of brown adipose tissue in male mice. Nat Commun 2023; 14:3746. [PMID: 37353518 PMCID: PMC10290150 DOI: 10.1038/s41467-023-39106-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 05/31/2023] [Indexed: 06/25/2023] Open
Abstract
Brown adipose tissue (BAT) has abundant mitochondria with the unique capability of generating heat via uncoupled respiration. Mitochondrial uncoupling protein 1 (UCP1) is activated in BAT during cold stress and dissipates mitochondrial proton motive force generated by the electron transport chain to generate heat. However, other mitochondrial factors required for brown adipocyte respiration and thermogenesis under cold stress are largely unknown. Here, we show LETM1 domain-containing protein 1 (LETMD1) is a BAT-enriched and cold-induced protein required for cold-stimulated respiration and thermogenesis of BAT. Proximity labeling studies reveal that LETMD1 is a mitochondrial matrix protein. Letmd1 knockout male mice display aberrant BAT mitochondria and fail to carry out adaptive thermogenesis under cold stress. Letmd1 knockout BAT is deficient in oxidative phosphorylation (OXPHOS) complex proteins and has impaired mitochondrial respiration. In addition, BAT-specific Letmd1 deficient mice exhibit phenotypes identical to those observed in Letmd1 knockout mice. Collectively, we demonstrate that the BAT-enriched mitochondrial matrix protein LETMD1 plays a tissue-autonomous role that is essential for BAT mitochondrial function and thermogenesis.

Med Oncol 2023; 40:184.

Abstract
A sustained increase in the mortality of pancreatic cancer (PC) and sudden metastasis-related mortality is a cause for concern. Aberrant expression of epidermal growth factor (EGF) receptor (EGFR) is noted in several cases of PC metastasis. The present study is aimed at analyzing the expression of EGFR in PC and its relevance to the progression of PC. Despite the number of studies that have shown the benefits of plumbagin on PC cells, its role on cancer stem cells remains largely unknown. To this end, the study used an EGF micro-environment to make cancer stem cells in vitro and ascertained the role of plumbagin in mitigating the actions of EGF. The kaplan-meier (KM) plot indicated reduced overall survival (OS) analysis in PC patients with high EGFR than low EGFR expression. Plumbagin pre-treatment significantly prevented EGF-induced survival, epithelial-to-mesenchymal transition (EMT), clonogenesis, migration, matrix metalloproteinase -2 (MMP-2) gene expression and its secretion, and matrix protein hyaluron production in PANC-1 cells. The computational studies indicate the greater affinity of plumbagin with different domains of EGFR than gefitinib. Several hallmarks of resistance and migration due to EGF are effectively attenuated by plumbagin. Collectively, these results warrant investigating the actions of plumbagin in a pre-clinical study to substantiate these findings.

Psoralidin inhibits osteosarcoma growth and metastasis by downregulating ITGB1 expression via the FAK and PI3K/Akt signaling pathways. Chin Med 2023; 18:34. [PMID: 37004120 PMCID: PMC10064721 DOI: 10.1186/s13020-023-00740-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Accepted: 03/27/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Psoralea corylifolia is a medicinal leguminous plant that has long been used to treat various diseases. Psoralidin (PSO) is the main extract compound of P. corylifolia and exhibits antibacterial, antitumor, anti-inflammatory, antioxidant, and other pharmacological activities. PSO has demonstrated inhibitory effects in several cancers; however, its inhibitory effect on osteosarcoma has not been reported. This study aimed to evaluate the inhibitory effect of PSO on osteosarcoma and elucidate the underlying molecular mechanisms. METHODS Crystal violet, cell counting kit-8 (CCK8), and 5-Ethynyl-2'-deoxyuridine (EdU) staining assays were used to assess the inhibitory effect of PSO on the proliferation of 143B and MG63 osteosarcoma cells. Wound healing and Transwell assays were conducted to evaluate the effects of PSO on osteosarcoma cell migration and invasion. The cell cycle and apoptosis were analyzed using flow cytometry. To determine the possible molecular mechanisms, RNA-sequencing was performed and protein expression was analyzed by western blotting. The inhibitory effect of PSO on osteosarcoma in vivo was analyzed using a mouse model of orthotopic osteosarcoma and immunohistochemistry. RESULTS PSO inhibited osteosarcoma cell proliferation in a concentration-dependent manner, inhibited cell migration and invasion, and induced cell-cycle arrest and apoptosis. Mechanistically, PSO treatment significantly inhibited the focal adhesion kinase (FAK) and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathways by downregulating ITGB1 expression in both MG63 and 143B cells. Furthermore, we demonstrated that PSO restrained osteosarcoma growth in vivo. CONCLUSION PSO may suppress osteosarcoma via the FAK and PI3K/Akt signaling pathways by downregulating ITGB1 expression.

Abstract
Human cervical cancer oncogene (HCCR-1), also named as LETMD1, is an LETM-domain containing outer mitochondrial membrane protein which plays an important role in carcinogenesis. The present study found that the loss of Letmd1 in mice led to severe abnormities, such as brown adipose tissue (BAT) whitening, impaired thermogenesis of both BAT and beige fat, cold intolerance, diet-induced obesity, glucose intolerance and insulin resistance. Mechanically, the deletion of Letmd1 in BAT caused decreased level of both mitochondrial and intracellular Ca2+. The reduced intracellular Ca2+ could suppress the fission of mitochondria and ultimately lead to the disruption of BAT thermogenesis by regulating mitochondrial structures and functions. This study indicates that LETMD1 played a crucial role in BAT thermogenesis and energy homeostasis through regulating mitochondrial structures and functions, which provides a novel insight into therapeutic target exploration from oncogenes for metabolic disorders.

Abstract
OBJECTIVE Human cervical cancer oncogene (HCCR)-1, previously identified in cervical cancer and its cell lines, has been reported to play an important role in tumor progression in several cancers as a suppressor of apoptosis. However, the role of HCCR-1 in the tumorigenesis of stomach cancer has not been identified. This study examined the role of HCCR-1 as a suppressor of apoptosis during tumorigenesis in gastric cancer, along with its possible regulatory pathway. METHODS We employed several techniques including western blotting, semiquantitative reverse transcription polymerase chain reaction, diphenyltetrazolium bromide assay, chromatin immunoprecipitation assay, fluorescence-activated cell sorting, and HCCR-1 knockdown with short hairpin RNA to elucidate the role of HCCR-1. RESULTS We observed that hepatocyte growth factor (HGF) upregulated HCCR-1 expression. In addition, the expression levels of β-catenin, T cell factor-1 (TCF1), and B-cell lymphoma 2 (bcl2) were increased, whereas that of tumor protein 53 (p53) was decreased following HGF treatment. HCCR-1 knockdown in NUGC-3 and MKN-28 cells decreased the expression of TCF1 and phosphorylated β-catenin and increased the binding activity on the binding site of the HCCR-1 promoter. This identifies the possible involvement of the Wnt/β-catenin pathway in HGF-induced HCCR-1 regulation. We also confirmed the role of HCCR-1 in HGF-induced anti-apoptotic activity. p53 protein expression was increased, whereas that of bcl2 was decreased with HGF treatment in HCCR-1 knockdown cells, while the apoptotic activity was increased. CONCLUSION Our study suggests the anti-apoptotic activity of HGF-induced HCCR-1 expression and that HGF may regulate HCCR-1 via TCF1/β-catenin in stomach cancer.

Abstract
Alnustone, a diarylheptane compound, exhibits potent growth inhibition against hepatocellular carcinoma (HCC) BEL-7402 cells. However, the underlying mechanisms associated with its anticancer activity remain unknown. In the present study, we evaluated the anticancer effect of alnustone against several human cancers focused on HCC and the possible associated mechanisms. The results showed that alnustone significantly inhibited the growth of several cancer cells by CCK-8 assay. Alnustone markedly induced apoptosis and decreased mitochondrial membrane potential in BEL-7402 and HepG2 cells. Alnustone inhibited the expression of proteins related to apoptosis and PI3K/Akt/mTOR/p70S6K pathways and generated ROS production in BEL-7402 and HepG2 cells. Moreover, N-acetyl-L-cysteine (NAC, a ROS inhibitor) could significantly reverse the effects of alnustone on the growth inhibition of BEL-7402 and HepG2 cells and the expression of proteins related to apoptosis and PI3K/Akt/mTOR signaling pathway in HepG2 cells. Furthermore, alnustone significantly inhibited tumor growth of HepG2 xenografts, obviously induced apoptosis in the tumor tissues and improved the pathological condition of liver tissues of mice in vivo. The study provides evidence that alnustone is effective against HCC via ROS-mediated PI3K/Akt/mTOR/p70S6K pathway and the compound has the potential to be developed as a novel anticancer agent for the treatment of HCC clinically.

Abstract
Background Recent studies have emphasized determining the ability of microRNAs (miRNAs) as crucial regulators in the occurrence and development of pancreatic cancer (PC), which continues to be one of the deadliest malignancies with few effective therapies. The study aimed to investigate the functional role of miR-135b and its associated mechanism to unravel the biological characteristics of tumor growth in pancreatic cancer stem cells (PCSCs). Methods Microarray analyses were initially performed to identify the PC-related miRNAs and genes. The expression of miR-135b and PCSC markers in PC tissues and cells was determined by RT-qPCR and western blot analysis, respectively. The potential gene (JADE-1) that could bind to miR-135b was confirmed by the dual-luciferase reporter assay. To investigate the tumorigenicity, migration, invasion, and stemness of PC cells, several gain-of-function and loss-of-function genetic experiments were conducted. Finally, tumor formation in nude mice was conducted to confirm the results in vivo. Results miR-135b was highly-expressed in PC tissues and PCSCs, which was identified to specifically target JADE-1. The overexpression of miR-135b promoted proliferation, migration, and invasion of PCSC, inhibited cell apoptosis and increased the expression of stemness-related factors (Sox-2, Oct-4, Nanog, Aldh1, and Slug). Moreover, miR-135b could promote the expression of phosphorylated AKT and phosphorylated mTOR in the AKT/mTOR pathway. Additionally, miR-135b overexpression accelerated tumor growth in nude mice. Conclusions Taken together, the silencing of miR-135b promotes the JADE-1 expression, which inactivates the AKT/mTOR pathway and ultimately results in inhibition of self-renewal and tumor growth of PCSCs. Hence, this study contributes to understanding the role of miR-135 in PCSCs and its underlying molecular mechanisms to aid in the development of effective PC therapeutics.

Clostridium butyricum, a butyrate-producing probiotic, inhibits intestinal tumor development through modulating Wnt signaling and gut microbiota. Cancer Lett 2019; 469:456-467. [PMID: 31734354 DOI: 10.1016/j.canlet.2019.11.019] [Citation(s) in RCA: 234] [Impact Index Per Article: 46.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 11/10/2019] [Accepted: 11/11/2019] [Indexed: 12/15/2022]
Abstract
Gut microbiota dysbiosis is closely involved in intestinal carcinogenesis. A marked reduction in butyrate-producing bacteria has been observed in patients with colorectal cancer (CRC); nevertheless, the potential benefit of butyrate-producing bacteria against intestinal tumor development has not been fully investigated. We found that Clostridium butyricum (C. butyricum, one of the commonly used butyrate-producing bacteria in clinical settings) significantly inhibited high-fat diet (HFD)-induced intestinal tumor development in Apcmin/+ mice. Moreover, intestinal tumor cells treated with C. butyricum exhibited decreased proliferation and increased apoptosis. Additionally, C. butyricum suppressed the Wnt/β-catenin signaling pathway and modulated the gut microbiota composition, as demonstrated by decreases in some pathogenic bacteria and bile acid (BA)-biotransforming bacteria and increases in some beneficial bacteria, including short-chain fatty acid (SCFA)-producing bacteria. Accordingly, C. butyricum decreased the fecal secondary BA contents, increased the cecal SCFA quantities, and activated G-protein coupled receptors (GPRs), such as GPR43 and GPR109A. The anti-proliferative effect of C. butyricum was blunted by GPR43 gene silencing using small interfering RNA (siRNA). The analysis of clinical specimens revealed that the expression of GPR43 and GPR109A gradually decreased from human normal colonic tissue to adenoma to carcinoma. Together, our results show that C. butyricum can inhibit intestinal tumor development by modulating Wnt signaling and gut microbiota and thus suggest the potential efficacy of butyrate-producing bacteria against CRC.

Abstract
The role of the human cervical cancer oncogene (HCCR-1) in the development of various tumors has been elucidated; however, its expression and function in gastric cancer remains largely unknown. Accordingly, the expression of HCCR-1 and epidermal growth factor (EGF) were detected in paired gastric cancer tissues and cell lines by western blotting (WB) and immunohistochemistry (IHC). Furthermore, the correlations between HCCR-1 expression in 209 gastric cancer tissues and the clinicopathological features and disease prognosis were analyzed. A stable HCCR-1 overexpression cell line was established, and the influence of increased HCCR-1 expression on the growth of gastric cancer cells was observed in vivo and in vitro. The expression of HCCR-1 generally increased in gastric cancer tissues. Further, increased HCCR-1 expression in gastric cancer tissues was associated with tumor T stage and was an independent factor that influenced poor postoperative prognosis in gastric cancer patients. A positive correlation was also detected between the expression of EGF and HCCR-1 in a time- and dose-dependent manner. The overexpression of HCCR-1 might enhance the growth rate of gastric cancer cells in vitro, increase the number of colony forming units, and promote the growth, volume, and weight of subcutaneous tumors in nude mice. In conclusion, HCCR-1 is a gastric cancer oncogene, and its increased expression plays a critical role in the occurrence and development of gastric cancer. Hence, HCCR-1 could serve as a valuable marker for the postoperative prognostic assessment of gastric cancer patients.

Overexpression of Na +/Mg 2+ exchanger SLC41A1 attenuates pro-survival signaling. Oncotarget 2017; 9:5084-5104. [PMID: 29435164 PMCID: PMC5797035 DOI: 10.18632/oncotarget.23598] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2017] [Accepted: 11/13/2017] [Indexed: 01/07/2023] Open
Abstract
The Na+/Mg2+ exchanger SLC41A1 (A1), a key component of intracellular Mg homeostasis (IMH), is the major cellular Mg2+ efflux system, and its overexpression decreases [Mg2+]intracellular. IMH plays an important role in the regulation of many cellular processes, including cellular signaling. However, whether the overexpression of A1 and the consequent drop of [Mg2+]i impact on intracellular signaling is unknown. To examine the latter, we utilized dynamic mass redistribution (DMR) assay, PathScan® RTK signaling antibody (PRSA) array, confirmatory Western blot (WB) analyses of phosphorylation of kinases selected by PRSA, and mag-fura 2-assisted fast filter spectrometry (FFS). We demonstrate here that the overexpression of A1 quantitatively and qualitatively changes the DMR signal evoked by the application of PAR-1-selective activating peptide and/or by changing [Mg2+]extracellular in HEK293 cells. PRSA profiling of the phosphorylation of important signaling nodes followed by confirmatory WB has revealed that, in HEK293 cells, A1 overexpression significantly attenuates the phosphorylation of Akt/PKB on Thr308 and/or Ser473 and of Erk1/2 on Thr202/Tyr204 in the presence of 0 or 1 mM (physiological) Mg2+ in the bath solution. The latter is also true for SH-SY5Y and HeLa cells. Overexpression of A1 in HEK293 cells significantly lowers [Mg2+]i in the presence of [Mg2+]e = 0 or 1 mM. This correlates with the observed attenuation of prosurvival Akt/PKB - Erk1/2 signaling in these cells. Thus, A1 expression status and [Mg2+]e (and consequently also [Mg2+]i) modulate the complex physiological fingerprint of the cell and influence the activity of kinases involved in anti-apoptotic and, hence, pro-survival events in cells.

Abstract
The activation of hepatic stellate cells (HSCs) is generally considered to be the central link in the formation of hepatic fibrosis. Various factors can regulate the function of HSCs through multiple signaling pathways, of which the mammalian target of rapamycin (mTOR) signaling pathway is especially important. Elucidating the relationship between the mTOR signaling pathway and the proliferation, apoptosis, autophagy, and senescence of HSCs can provide new therapeutic targets and methods for the clinical treatment of hepatic fibrosis. This paper discusses the relationship between the mTOR signaling pathway and the function of HSCs.

Abstract
Ilex Rotunda Thunb has been shown to have anti-inflammatory and antioxidant effects. In human keratinocytes, we investigated the effect of rotundarpene (4-caffeoyl-3-methyl-but-2-ene-1,4-diol) on the TNF-α-stimulated production of inflammatory mediators in relation to the Akt, mTOR, and NF-κB pathways, and the JNK and p38-MAPK. Rotundarpene, Akt inhibitor, Bay 11-7085, rapamycin, and N-acetylcysteine inhibited the TNF-α-stimulated production of cytokines and chemokines, increase in the levels of p-Akt and mTOR, activation of NF-κB, and production of reactive oxygen species in keratinocytes. TNF-α treatment induced phosphorylation of the JNK and p38-MAPK. Inhibitors of the c-JNK (SP600125) and p38-MAPK (SB203580) reduced the TNF-α-induced production of inflammatory mediators, binding of NF-κB to DNA, and activation of the JNK and p38-MAPK in keratinocytes. The results show that rotundarpene may reduce the TNF-α-stimulated inflammatory mediator production by suppressing the reactive oxygen species-dependent activation of the Akt, mTOR, and NF-κB pathways, and activation of the JNK and p38-MAPK in human keratinocytes. Additionally, rotundarpene appears to attenuate the Akt, mTOR, and NF-κB pathways and the JNK and p38-MAPK-mediated inflammatory skin diseases.

Abstract
Hepatocellular carcinoma (HCC) is one of the most fatal human malignancies, Human cervical cancer proto-oncogene (HCCR) aberrantly expressed in a number of malignant tumors, including HCC. HCC is associated with Hepatitis B virus (HBV) infection in a large percentage of cases. To explore the regulation and function of HCCR expression in the development of HCC, we detected HCCR expression in HBV expressing hepatocytes. Results showed that the expression of HCCR was higher in HBV-expressing hepatocytes than that in control cells. Examining different components of HBV revealed that the HBx promotes HCCR expression in hepatocytes via the T-cell factor (TCF)/β-catenin pathway. HCCR expression in HBx transgenic mice increased with as the mice aged and developed tumors. We also found that overexpression of HCCR in hepatocytes promoted cell proliferation, migration, and invasion and reduced cell adhesion. Suppressing HCCR expression abolished the effect of HBx-induced hepatocyte growth. In addition, HCCR represses the expression of E-cadherin by inhibition its promoter activity, which might correlate with the effects of HCCR in hepatocytes. Taken together, these results demonstrate that HBx-HCCR-E-cadherin regulation pathway might play an important role in HBV-induced hepatocarcinogenesis. They also imply that HCCR is a potential risk marker for HCC and/or a potential therapeutic target.

Abstract
Human cervical cancer oncogene (HCCR) was identified by differential display RT-PCR by screened abnormally expressed genes in cervical human cancers. The overexpressed gene is not only identified in cervical tissues, but also in various human cancers as leukemia/lymphoma, breast, stomach, colon, liver, kidney and ovarian cancer. For its special sensitivities and specificities in human breast cancer and hepatocellular carcinoma, it is expected to be a new biomarker to replace or combine with the existing biomarkers in the diagnose. The HCCR manifests as a negative regulator of the p53 tumor suppressor gene, and its expression is regulated by the PI3K/Akt signaling pathway, modulated by TCF/β-catenin, it also participates in induction of the c-kit proto-oncogene, in activation of PKC and telomerase activities, but the accurate biochemical mechanisms of how HCCR contributes to the malignancies is still unknown. The aim of this review is to summarize the roles of HCCR in cancer progression and the molecular mechanisms involved.

Abstract
OBJECTIVE This study was to explore the expression of human cervical cancer oncogene-1 (HCCR-1) in colon cancer and its clinical significance. METHODS RT-PCR, immunohistochemistry and Western blot assay were employed to detect HCCR-1 expression in 152 colon cancers, 43 adjacent non-cancerous tissues and 37 normal tissues. In addition, immunohistochemistry was done to detect CEA in colon cancers. RESULTS The mRNA expression of HCCR-1 in colon cancers was higher than that in the adjacent non-cancerous tissues (P < 0.05), and the mRNA expression of HCCR-1 in adjacent non-cancerous tissues was higher than that in normal tissues (P < 0.05). The positive rate of HCCR-1 in colon cancers was 80.9%, which was higher than that in adjacent non-cancerous tissues (P < 0.05). Almost no HCCR-1 expression was observed in normal tissues, weak expression in adjacent non-cancerous tissues and strong expression in colon cancers. The positive rate of HCCR-1 in colon cancer at Duke stage B-C was 87.3%, which was higher than that in stage A colon cancer (63.6%, P < 0.05). CONCLUSION HCCR-1 is over-expressed in colon cancers, indicating that HCCR-1 may participate in occurrence and development of colon cancer and has a correlation with the pathological progress of colon cancer progression.

Abstract
The human cervical cancer oncogene (HCCR) has been shown to be over-expressed in some solid tumors, and its function is involved in negative regulation of p53 tumor suppressor gene. However, the roles of HCCR in leukemia remain unclear. The present study is to investigate whether the expression levels of HCCR mRNA are associated with clinical prognosis in patients with acute leukemia (AL) and to explore the potential use as a biomarker for monitoring minimal residual disease (MRD) in AL. The mRNA levels of HCCR1 and HCCR2 were quantified by real-time reverse transcription polymerase chain reaction in bone marrow samples from 80 adult de novo AL patients and 20 normal healthy donors. The expressions of HCCR1 and HCCR2 were significantly higher in patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) than those in healthy donors (P < 0.01), but there was no significant difference between AML and ALL (P > 0.05). Besides white blood cell count, we did not find any significant correlation between HCCR expression and clinical characteristics, such as age, sex, CD34 antigen expression, and response to chemotherapy. HCCR was monitored in 12 cases during remission and/or relapse. Significant reductions of both HCCR1 and HCCR2 mRNA levels were observed in patients who had achieved complete remission after chemotherapy but not in patients with non-responsive. However, an increased HCCR expression was detected in these patients who relapsed. Our findings suggest that HCCR gene is over-expressed in AL patients and may be as a useful biomarker for monitoring MRD in AL.

Abstract
Pancreatic cancer is a uniformly lethal disease that can be difficult to diagnose at its early stage. Thus, our present study aimed to explore the underlying mechanism and identify new targets for this disease. The data GSE16515, including 36 tumor and 16 normal samples were available from Gene Expression Omnibus. Differentially expressed genes (DEGs) were screened out using Robust Multichip Averaging and LIMMA package. Moreover, gene ontology and pathway enrichment analyses were performed to DEGs. Followed with protein-protein interaction (PPI) network construction by STRING and Cytoscape, module analysis was conducted using ClusterONE. Finally, based on PubMed, text mining about these DEGs was carried out. Total 274 up-regulated and 93 down-regulated genes were identified as the common DEGs and these genes were discovered significantly enriched in cell adhesion and extracellular region terms, as well as ECM-receptor interaction pathway. In addition, five modules were screened out from the up-regulated PPI network with none in down-regulated network. Finally, the up-regulated genes, including MIA, MET and CEACAMS, and down-regulated genes, such as FGF, INS and LAPP, had the most references in text mining analysis. Our findings demonstrate that the up- and down-regulated genes play important roles in pancreatic cancer development and might be new targets for the therapy.

Abstract
AIM: To investigate the role of transformation growth factor-β1 (TGF-β1) in the therapeutic effect of rapamycin on liver fibrosis in rats.
METHODS: Rats were divided into three groups: a normal control group, a liver fibrosis model group and a rapamycin treatment group. Rats were treated with carbon tetrachloride to induce liver fibrosis. Eight weeks after treatment, liver histological changes and the expression of TGF-β1 in the liver were detected. In addition, serum TGF-β1 levels were dynamically monitored.
RESULTS: After immunohistochemical and HE staining, image-pro plus 6 image analysis software was used to analyze the integrated absorbance (IA). The IA values were 9891.4 ± 1725.7, 104239.9 ± 20890.6, and 27853.6 ± 2031 in the normal control group, liver fibrosis model group and rapamycin treatment group, respectively. The expression of TGF-β1 in liver tissue was significantly different among the three groups (P < 0.01).
CONCLUSION: Rapamycin can significantly reduce the levels of TGF-β1 in liver tissue and serum, which may be involved in the therapeutic effect of rapamycin on liver fibrosis.

Abstract
OBJECTIVES Obesity-associated carcinogenesis is postulated to be mediated through the proliferative actions of insulin and the insulin-like growth factor (IGF) family. The aim of this study was to determine whether the insulin/IGF-1 pathway is involved in the sequential progression from metaplastic Barrett's esophagus (BE) to dysplasia to esophageal adenocarcinoma (EAC). METHODS Fasting serum levels of insulin, glucose, IGF-1, insulin growth factor binding protein-1 (IGFBP1), and IGFBP3 were measured in 44 non-dysplastic, 9 low-grade dysplasia (LGD), 12 high-grade dysplasia (HGD), and 10 EAC subjects. Immunohistochemistry was performed on paraffin-embedded tissue derived from BE cases using rabbit monoclonal antibodies to p-mammalian target of rapamycin (mTOR) and p-AKT, mouse monoclonal antibody to Ki-67, and rabbit polyclonal antibody to p-insulin receptor substrate 1 (IRS1). RESULTS Nineteen of 44 (43.2%) BE, 5/9 (55%) LGD, 8/12 (66.7%) HGD and EAC 7/10 (70%) cases showed strong staining for p-IRS1. A significantly higher proportion of HGD/EAC subjects showed p-IRS1 staining when compared with BE/LGD subjects, 63.6% vs. 41.5%, P<0.05. p-IRS1 immunostaining was moderately correlated with strong immunostaining of the downstream mediators p-AKT and p-mTOR (Spearman correlation coefficient=0.167 and 0.27 for p-IRS1/p-AKT and for p-IRS1/p-mTOR, respectively) and the proliferation marker Ki-67 (Spearman correlation coefficient=0.20, P=0.09). However, systemic levels of insulin, IGF-1, or IGF-2 were not associated with tissue immunostaining of p-IRS1. CONCLUSIONS Activation of the insulin/IGF-1 pathway in BE may be associated with cellular proliferation and appears to have a role in the progression from metaplasia to cancer. The activation of the insulin/IGF-1 pathway at the tissue level is likely complex and does not have a simple association with systemic measures of insulin or IGF-1.

Abstract
The phosphoinositide-3 kinase (PI3K)-AKT-mammalian target of rapamycin (mTOR) pathway is a cellular pathway involved in cell growth, tumorigenesis and cell invasion which is frequently activated in various types of cancer. The downstream effector of the pathway is mTOR which is important in cellular growth and homeostasis and aberrant activation of mTOR has been reported in several types of cancer. The tumor suppressor gene phosphatase and tensin homolog (PTEN) is essential in this pathway for inhibiting tumor invasion and metastasis. However, the involvement of mTOR and PTEN in the progression of human gastric cancer remains to be identified. Immunohistochemical staining was performed to detect the expression of mTOR and PTEN in paraffin-embedded gastric tissue sections obtained from 33 patients with gastric cancer and 30 normal controls. The expressed mTOR was mainly distributed in the cytoplasm, while PTEN was mainly localized to the nucleus. By considering negative mTOR expression with positive PTEN expression as one group and negative PTEN expression with positive mTOR expression as the other, significant statistical differences were observed in various categories, including histological types and metastatic and clinical pathology stages, between the 2 groups (P<0.01 or 0.05). The results indicated that the expression levels of mTOR and PTEN were negatively correlated in the PI3K-AKT-mTOR signaling pathway. Combined detection of mTOR and PTEN expression may be used to evaluate the degree of malignancy in gastric cancer and may be a useful marker for the early diagnosis of gastric cancer.

Abstract
The human cervical cancer oncogene 1 (HCCR-1), a novel human oncoprotein, has been shown to be upregulated in various human tumors and plays a critical role in tumorigenesis and tumor progression. Here, the authors investigated HCCR-1 level in esophageal squamous cell carcinoma (ESCC) tissues and assessed the correlation between HCCR-1 level and prognosis of the patients with ESCC. HCCR-1 levels were investigated by immunohistochemistry, in situ hybridization, real-time quantitative RT-PCR and Western blotting methods; Kaplan-Meier curve was used to evaluate the prognostic value of HCCR-1 level in patients with ESCC using log-rank test. HCCR-1 displayed high levels in ESCC tissues compared to squamous dysplasia tissues and normal esophageal epithelial tissues. No significant correlation was observed between the levels of HCCR-1 mRNA and protein and gender and age (all p>0.05) but obviously related to histological grade, clinical stage, and lymph node metastasis (all p<0.001). Moreover, the survival rate of the patients with low HCCR-1 levels was higher than that of the patients with high HCCR-1 levels (both p<0.05). These data demonstrate that HCCR-1 may be used as a novel predictor for the prognosis of the patients with ESCC.

Abstract
In the past years, free fatty acids (FFAs) and obesity have been reported to play an important role in cancer development. Palmitic acid (PA) is the most prevalent saturated FFA in circulation. However, the mechanism underlying the effect of PA on cell proliferation is still to be elucidated. In this report, we, for the first time, investigate the signaling pathway in human normal hepatocytes (QZG) responsible for PA-induced proliferation. The results demonstrate that PA promotes cell cycle progression, accelerates cell proliferation, and induces a transient and sequential activation of a series of kinases. The employment of several inhibitors and antioxidants indicates that a ROS-induced stress-sensitive p38 MAPK/ERK-Akt cascade plays a critical role in the regulation of PA on cell cycle and cell proliferation. Moreover, PA dose and time dependently activates Nrf2 and this activation relies on ROS-induced stimulation of p38 MAPK/ERK-Akt signaling, demonstrating that Nrf2 activation may be associated with the regulation of PA on cell cycle transition and proliferation. In conclusion, our study elucidates the importance of PA metabolism on cell proliferation, and suggests that PA stimulates hepatocyte proliferation through activating the ROS-p38 MAPK/ERK-Akt cascade which is intersected with the activation of Nrf2 and that the effect of ROS on signal transduction is in a dose- and time-dependent manner. All the above noted provide a new clue for the central role of ROS in cell proliferation and tumorigenesis.

Abstract
BACKGROUND Pancreatic cancer is a highly malignant cancer and the fourth leading cause of cancer-related death. It is characterized by a rapid disease progression, a highly invasive tumor phenotype, and frequently resistance to chemotherapy. Despite significant advances in diagnosis, staging, and surgical management of the disease during the past decade, prognosis of pancreatic cancer is still dismal. METHODS AND RESULTS The phosphatidylinositol 3-kinase (PI3K) signaling pathways regulate cellular growth, metabolism, survival, and motility in pancreatic cancer. Pancreatic cancer is associated with a high degree of genetic alterations that can result in aberrant activation of the PI3K signaling pathway. Elucidating the role of the PI3K signaling pathway in pancreatic cancer may thus be both meaningful and necessary. CONCLUSION Improved knowledge of the PI3K signaling pathway in pancreatic cancer would furthermore be helpful in understanding mechanisms of tumor initiation and progression, and in identifying appropriate targeted anticancer treatment in pancreatic cancer. and IAP.
